FLOW CONTROLS
FR16-20F Regulator, Pressure-Compensated
DESCRIPTION
A screw-in, cartridge-style, fixed orifice, pressure-compensated, hydraulic flow
regulating valve (restrictive type).
OPERATION
The FR16-20F maintains a constant flow rate out of ➁ regardless of load pressure
changes in the circuit downstream of ➁.
The fixed control orifice is factory preset to customer flow specification. The valve
begins to respond to load changes when the flow through the valve creates a
pressure differential across the control orifice greater than 5.5 bar (80 psid), with
accurate flow maintenance from 7.6 to 240 bar (300 to 3500 psid). Reverse flow
(➁ to ➀) returns through the control orifice and is non-compensated.
FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
• Cost-effective cavity.
